Thank you in advance!! 

Sketch P-v Diagram, Sketch T-s Diagram, Determine heat addition for process 2-3 (KJ/Kg), Determine heat reject for process 1-2 (KJ/Kg), and  Determine total expansion work done by the gas (KJ/Kg) 

 

A power cycle for a piston-cylinder device is described by the following four processes
1-2 Isothermal compression from 300 K, 100 kPa to 600 kPa
2-3 Constant pressure heat addition until the temperature is 800 K
3-4 Isentropic expansion until the volume at state 4 equals the volume at state 1.
4-1 Constant volume heat rejection until the temperature is 300 K.
Assume the working fluid is an ideal gas with constant specific heats and has properties as follows:
Cv = 0.6 kJ/(kg-K), Cp = 0.84 kJ/(kg-K), R = 0.3 kJ/(kg-K), k= 1.4
